Abstract

A device for processing faults, that detects and identifies faults, including, for at least part of the identified faults: a mechanism storing a log of occurrences of faults having a same identification, in a course of a plurality of flights; a mechanism determining an impact of each identified fault, on availability of aircraft in a predetermined duration, a mechanism associating a hierarchical attribute with each fault detected in a course of a flight, the hierarchical attribute being dependent on the log and on the impact; and a mechanism displaying identified faults associated with part of the hierarchical attributes. The device enables, in particular, maintenance operations or operations preparatory to maintenance to be better scheduled by virtue of hierarchization of faults displayed.

Claims

1-14. -14. (canceled)

15. A device for processing failures, comprising:

means for detecting and identifying failures; and

,

for at least one part of the identified failures;

a means for storing a history of occurrences of failures having a same identification, in a course of a plurality of flights;

a means for determining an impact of each identified failure on availability of an airplane in a predetermined period;

a means for associating a hierarchical attribute with each failure detected in a course of a flight, the hierarchical attribute being dependent on the history and the impact; and

a means for displaying identified failures that are associated with a part of the hierarchical attributes.

16. A device according to claim 15, further comprising a means for determining status, ongoing or intermittent, of each identified failure, according to the history of the failure in a course of at least one preceding flight, the means for associating a hierarchical attribute with each failure detected in the course of a flight being adapted so that the hierarchical attribute is dependent on the status.

17. A device according to claim 16, wherein the means for determining the status, ongoing or intermittent, of each identified failure, uses a category of each identified failure message.

18. A device according to claim 15, further comprising a means for receiving a history of occurrence of a failure from a tool on the ground, the means for storing a history of occurrence of failures having a same identification storing the history.

19. A device according to claim 15, wherein the means for determining the impact of each identified failure on the availability of the airplane uses a category for each identified failure.

20. A device according to claim 15, wherein the means for associating a hierarchical attribute with each failure detected in the course of a flight is adapted so that the hierarchical attribute is representative of failures having an impact that grounds the airplane, and the display means is adapted for displaying the failures.

21. A device according to claim 15, wherein the means for associating a hierarchical attribute with each failure detected in the course of a flight is adapted so that the hierarchical attribute is representative of failures having an impact that would ground the airplane if their status became ongoing in a predetermined period.

22. A device according to claim 15, wherein the means for associating a hierarchical attribute with each failure detected in the course of a flight is adapted so that the hierarchical attribute is representative of failures occurring in the course of at least a first predetermined number of flights, among a second predetermined number of flights made by the airplane, and the display means is adapted for displaying the failures.

23. A device according to claim 22, wherein the first and/or second predetermined numbers are dependent on the identification of the failure.

24. A device according to claim 15, wherein the means for associating a hierarchical attribute with each failure detected in the course of a flight is adapted so that the hierarchical attribute is representative of failures capable, in combination with another failure not yet occurring, of grounding the airplane, and the display means is adapted for displaying the failures.

25. A device according to claim 15, wherein the means for associating a hierarchical attribute with each failure detected in the course of a flight is adapted so that the hierarchical attribute is representative of failures capable of grounding the airplane after a predetermined number of flying hours, and the display means is adapted for displaying the failures.

26. An airplane, comprising a device according to claim 15.

27. A system for processing failures on the ground, comprising a device according to claim 15.

28. A method for processing errors detected and identified by means for detecting and identifying, failures comprising, for at least a part of the identified failures:

storing a history of occurrences of failures having a same identification, in a course of a plurality of flights;

determining an impact of each identified failure on availability of an airplane in a predetermined period;

associating a hierarchical attribute with each failure detected in a course of a flight, the hierarchical attribute being dependent on the history and the impact; and

displaying identified failures that are associated with a part of the hierarchical attributes.
